Trelleborg’s Seal Materials Tested for Optimum Performance

Trelleborg Sealing Solutions has carried out a series of tests to show the importance of fluid type and seal material choice in “ensuring optimum seal performance and service life”.

Seal Material Testing

The world leader in engineered polymer solutions, which has been making highly developed seals for over 30 years, worked with fluid producer MacDermid to test the effect of water glycol fluids (HFC) on common seal materials.

Together the engineers for both companies tested seven seal materials which were immersed in water glycol fluids at a range of elevated temperatures up to +200°C / +392°F.

ONS Conference white paper on results
The results have been published in a white paper on the subject which will be available to collect from Trelleborg’s stand in Hall 9 at the ONS Conference in Norway from August 29 to September 01.

Each seal and fluid combination was tested for hardness change, tensile strength change, strain change and volume change. All physical changes were documented using before and after photos.

Importance of fluid and material choices
David Brown, Global Lead Group Director, Oil & Gas, Trelleborg Sealing Solutions, says: “The testing reveals the importance of fluid type and seal material choice in ensuring optimum seal performance and service life. Traditional sealing materials, such as FKM, often inert in most fluids, are exhibiting disadvantageous behaviour in HFC fluids.

“Offshore operators are free to add extra additives to suit their particular application, but these could lead to seal material incompatibilities and cause dramatic adverse effects on sealing materials.

“We recommend each application must be reviewed uniquely to optimize the seal materials with the HFC fluid to ensure seal performance and life.”

Developed in-house
The series of tests were developed by Trelleborg Sealing Solutions in 2015.

Seal Materials Testing Laboratory

The company decided to investigate the effects of high-temperature exposure of sealing materials within water-based hydraulic fluids because until now, the two materials have never been thoroughly tested together at high temperatures before.

Water-based hydraulic fluids are widely used in oil and gas, mining, hot-rolling mills, and similar applications where the potential for fire could cause catastrophic consequences.

They are also replacing traditional oil-based HLP fluids in applications where environmental regulations must be observed.

As a result, they have become more prevalent in many applications within offshore energy production as a means of protecting people, the environment and resources.

HFC fluids
The International Standards Organization (ISO) classifies fire-resistant, water-based hydraulic fluids into four categories which include HFAE, HFAS, HFB and HFC.

HFC fluids are the most common hydrous, fire-resistant hydraulic fluids because they have the best fire resistance and hydraulic properties. They are also used wherever hydraulic fluid escaping under high pressure can ignite on contact with hot materials.

The fire resistant and environmentally friendly qualities of HFC fluids make them ideal for use in offshore installations.

The fire-resistant properties mean greater fire safety, offering more time to initiate fire-fighting measures and bring people to safety in the event of an accident.

Trelleborg and Jetseal Inc. Sign Distribution Agreement for Aerospace Metallic Seals

Trelleborg Sealing Solutions and Jetseal Inc. are proud to announce the signing of an exclusive distribution agreement for advanced specialty metallic aerospace seals covering the whole of the European aerospace market.

Aerospace Metallic Seals









The recently signed distribution agreement combines the wide aerospace market presence of Trelleborg Sealing Solutions with the highly engineered metallic seals expertise of HEICO’s Jetseal, Inc.

Michel Prouff, Director Global Marketing Aerospace for Trelleborg Sealing Solutions, says: “Trelleborg Sealing Solutions continues to rapidly expanding into the European aerospace engine market and this new distribution agreement with Jetseal Inc. offers significant market opportunities for both companies.”

In addition to its wide range of aerospace seals, Trelleborg Sealing Solutions is now offering a full line of metallic seals, ranging from industry standard AS1895 e-seals to complex multi-convolution seals for sealing high pressure and temperature engine applications. Additionally, the new partnership will allow Trelleborg Sealing Solutions to offer seals for use in the hot section of the turbine engine up to +750 °C.

Trelleborg Unveils Unique Primary Flight Control Seal Test Bench at FIA2016

Trelleborg Sealing Solutions announces its new Primary Flight Control Seal Test Bench at FIA 2016 (Farnborough International Airshow) held in Hampshire, UK, from July 11-17.

Flight Control Sealing Arrangement

Located in the HA Traub Technical Center in Fort Wayne, Indiana in the U.S., this test equipment can uniquely offer a rapid multi-million cycle testing capability, considerably shortening the proving time of flight control applications.

The Flight Control Seal Test Bench will globally support designers in the evaluation of piston and rod seal designs or entire packages before hardware is available. It can test conditions that are either difficult or expensive to replicate in the real world, improving the quality of the system early in the design stage, reducing the number of errors found later and building customer confidence in seal performance.

Innovation leader in aerospace

Primary Flight Control Seal TestGregory Jones, Trelleborg Sealing Solutions General Manager, Aerospace Hub Americas (AHA), says: “Trelleborg Sealing Solutions continues to be the innovation leader in sealing solutions for aerospace. The Primary Flight Control Seal Test Bench is the only system available in the world that tests either rod or piston hydraulic seals under extreme environmental and motion conditions combined with a multi-million cycle capability.”

The Primary Flight Control Seal Test Bench can simulate a large combination of extreme operating conditions. The test equipment is rated for static or cyclic pressures up to 5,000 psi/ 345 bar. It is fully capable of dynamic operation across the entire phosphate ester fluid operating temperature range of -80 °F to +325 °F/ -62 °C to +163 °C, testing a seal’s endurance against all thermal conditions. It creates a controlled environment where seals can be continuously stressed and monitored as necessitated by the customer and corresponding to their specific application challenges.

Primary Flight Control Test Bench
A distinguishing capability of the test equipment is achieving pressure rise rates of up to 360,000 psi/second/ 24,800 bar/second enabling accelerated high frequency cycling up to 5 Hz, even under maximum pressure or temperature conditions. This accelerated cycle speed allows for multi-million cycle fatigue testing to occur in just weeks rather than months. Since conditions change over a seal’s life, the Primary Flight Control Test Bench uses nested loop automation to change and repeat stroke lengths, speeds, pressures, frequencies, and cycle counts within seconds to simulate an entire range of flight or quality conditions, all without operator input or delay.

As the leader in Elastomer, polytetrafluoroethylene (PTFE) based and airframe seals, Trelleborg products are used in virtually every major aircraft program. Trelleborg Sealing Solutions continues to enhance seal designs and is able to test and validate its newest innovations for a wide variety of systems, including primary and secondary flight control sealing systems, actuation, landing gear, wheels, brakes, fuel controls, engines and airframe. Advanced sealing polymers and seal profiles for flight control sealing applications can undergo vigorous tests using the Flight Control Seal Test Bench to surpass higher pressure, wear and friction challenges and to achieve increased flight hours, speeds and safety.

During FIA 2016, attendees are invited to visit Trelleborg Sealing Solutions at stand A60 in Hall 4 to discuss application solutions and projects with our seal technology experts.
